Be it known that I, Joslin LQHRMANN, a citizen of' the ('ern'ian Empire, and resident of Dusseldorf, lGeri'nany, have invented certain new and useful improvements in later-Purifiers, of whichthe` following is a specification.

My invention relates to improvements in water purifiers ot' the class which is used in high-pressure and low-pressure water-conduits and the object of nay-invention is to provide ran improved device of the class referred to which is of plain construction, permits an easy and convenient cleaning and shows certain other advantages hereinbelow specified.

In describing my .invention I' refer to the drawing herewith in whichl l Figure 1 isa vertical transverse section through my improved purifier while Fig. 2 shows a similar device, also in vertical crosssection, slightly modified, but Within the spirit and scope of ymy invention.

My new water purifier comprises a vessel a adapted for insertion in and communism tion with or attachment to a main or other conduit pipe. It contains a plurality of strainers of cylindrical or other suitable shape which are so disposed within the ysaid vessel 'that the water is 4forced to pass through one and then the other, or-others, to separate any impurities, as sand, mud or the like. In the drawing two strainers, one within the other, are' shown in each iigure, the innermost strainer being marked o and the oneinclosing it c. The strainers may be made of perforated sheet-metal, preterably copper or brass, the whole passage of the perforations in each strainer being larger than that. .of the conduit-pipe. The main ofice of the strainer c, or strainers, inclosing the innermost strainer, is to prevent the water from leaving the -vessel a unpurified, in case the inner. strainerl or strainers or any of them should become spoiled or injured. The outer strainer@ may be without bottom and is mounted on a shoulder 7c provided foi; the purpose in the bottom of the vessel a. The intermediate space between any two strainers may on top be covered by a suitable cover, as a ring b1 or the likeand there may be a spring. j' se cured to and "acting against the said ring or against an intermediate cross-head 712, or the like, thcreabove thus causing the said ring b1 to firmly press and seal the top end -taken out for the purpose.

each other, I'pnefer them to beat one level, as shown; 1n both igures on the drawing,

because in this case the vessel may be more conveniently adjoined to the water conduit direct Without requiring an intermediate knee'or elbow piece.

The aforesaid innermost strainer b may have a bottom, as shown in Fig. l; it may, however, as well be Without a bottom and mounted on a shoulder Z provided within the vessel a against which it is pressed vby 'the aforesaidspring f. i

The vessel a. is on top closed by a cover d which may be taken QE to permiteJ cleaning ofthe inner strainer o which may be necessary, however, if a strainer b without a bottom is used, as in Fig. 2i, as in this case it may be conveniently washed out on rel moving the plug. or screw` g inthe bottom end of the vessel a. Moreover, the bottom.'-

`Within the 'innermost strainer may""i'bef placed lubricant ofzsnitable consistency., 'whereby the water passing 'throughi-said strainer will receive, some of said lubricant for use beyond the strainer.
